Anatomical left‐right asymmetry of language‐related temporal cortex is different in left‐ and right‐handers
Abstract
Asymmetry of the planum temporale, a language‐related intrasylvian area on the superior temporal gyrus, is the most remarkable anatomical left‐right asymmetry of the human brain. The in vivo application of magnetic resonance morphometry in 52 healthy volunteers (26 dextrals and 26 sinistrals) revealed that planum temporale asymmetry than right‐handers. Thus, a structural‐functional relation exists in cerebral asymmetry. The correlation is likely to reflect language representation. Because familial sinistrality influenced the anatomical pattern in left‐handers and planum temporale asymmetry is already present in the newborn, prenatal factors must play an important role in the development of functional laterality.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
